METHODS (ADDITIONAL DETAILS)
Study design
The study was conducted in academic and clinical research centres in Europe, North
America, South America, Asia (Philippines, Japan, India), Australia, China, Taiwan and
South Africa.
During washout, patients discontinued long-acting bronchodilator therapy: at least seven days
for long-acting muscarinic antagonists and the long-acting β2-agonist (LABA) indacaterol,
and 48 hours for all other LABAs and LABA/inhaled corticosteroid (ICS) combinations.
Concomitant medications permitted during the SHINE study are detailed in appendix table 2.
Screening tests were performed and baseline electronic diary data collected during a 14-day
run-in period.
Randomisation and blinding
Eligible patients were assigned a randomisation number via Interactive Response Technology
(IRT), linking the patient to a treatment arm and specific unique medication number for the
study drug. The randomisation number was not communicated to the investigator contacting
the IRT. Patients randomised to open-label tiotropium were not assigned a medication
number as this treatment was supplied locally. Randomisation was stratified by baseline
smoking status and ICS use.
Blinding of patients, investigator staff, personnel performing assessments and data analysts
was maintained by ensuring randomisation data remained strictly confidential and
inaccessible to anyone involved in the study until the time of unblinding. In addition, the
identity of the treatments was concealed by the use of study drugs that were all identical in
packaging, labelling, and schedule of administration, appearance, taste and odour. Unblinding
occurred in the case of emergencies and at the conclusion of the study. The bioanalyst of the
pharmacokinetic samples was unblinded.
Statistical methods
Statistical power
For the primary endpoint, 1710 evaluable patients gave 87% power for QVA149 versus the
mono-components, >99% power for active drugs versus placebo, and 80% power for noninferiority of QVA149 versus tiotropium. A standard deviation of 245 mL was assumed for
trough forced expiratory volume in 1 second (FEV1) and a treatment difference in trough
FEV1 of 120 mL (minimally clinically important difference [MCID]) was assumed for active
versus placebo, 60 mL (1/2 MCID) for QVA149 versus the mono-components and a noninferiority margin of 40 mL (1/3 MCID) for QVA149 versus tiotropium. This sample size
also gave adequate power for the three key secondary endpoints (Transition Dyspnoea Index
[TDI] focal score, 92%; St George’s Respiratory Questionnaire [SGRQ] total score, 81%;
rescue medication use, >99%).
Statistical analyses
Efficacy analyses were conducted on all randomised patients who received at least one dose
of study drug (full analysis set [FAS]) according to treatment assignment at randomisation.
The safety set comprised all patients receiving at least one dose of study drug; patients were
analysed according to the treatment they received.
2
The primary variable of trough FEV1 at Week 26 (with missing values imputed with last
observation carried forward [LOCF]) was analysed for the FAS using a mixed model with
treatment as a fixed effect and covariates of baseline FEV1, FEV1 before and after salbutamol
and ipratropium inhalation. The model also included baseline smoking status (current/exsmoker), baseline ICS use (yes/no) and region as fixed effects with centre nested within
region as a random effect. Estimated treatment differences are presented as least squares
means (LSM) with standard errors, and associated 95% confidence intervals (CI). Superiority
of QVA149 versus indacaterol or glycopyrronium was demonstrated if the adjusted one-sided
p-value was less than the multiplicity adjusted significance level. Key and important
secondary efficacy variables were analysed using the same method as for the analysis of the
primary variable, with Baseline Dyspnoea Index, baseline SGRQ or baseline rescue
medication use replacing the baseline FEV1 covariate as appropriate. Superiority of QVA149
and other active treatments versus placebo, and non-inferiority of QVA149 versus tiotropium
(for trough FEV1) was demonstrated if the adjusted one-sided p-value was less than the
multiplicity adjusted significance level. Non-inferiority of QVA149 versus tiotropium was
evaluated for the per-protocol set (non-inferiority criterion, 40 mL treatment difference); all
other treatment comparisons were evaluated for the FAS. Other secondary efficacy variables
were analysed using similar methods, with appropriate baseline measurements as covariates
and no adjustment for multiplicity was made. For the responder analyses of dyspnoea and
health status performed using logistic regression, the estimated adjusted odds ratios are
displayed along with the associated 95% CIs and two-sided p-values. Analyses of trough
FEV1 at Week 26 performed in subgroups divided according to age, gender, disease severity,
and ICS use, included appropriate interaction terms and additional covariates as appropriate
in the analysis model, and no adjustment for multiplicity was made. Adverse events and other
safety endpoints are presented using descriptive statistics.
RESULTS (ADDITIONAL DETAILS)
Spirometry
Increase from baseline in trough FEV1 at Week 26
All active treatments at Week 26 (LOCF) had an increase from baseline in trough FEV1, the
mean increase being highest for the QVA149 group (0.16 L, +15.3%); mean change from
baseline for indacaterol was 0.08 L (+7.7%); glycopyrronium 0.07 L (+7.1%), and tiotropium
0.09 L (+9.3%).
Post-hoc analyses of the primary endpoint
Post-hoc analyses indicated that the proportion of patients with an increase of >100 mL in
trough FEV1 at Week 26 (LOCF) from baseline was greater for QVA149 (64.3%) compared
with indacaterol (46.2%), glycopyrronium (43.2%), tiotropium (46.6%) and placebo (18.9%),
(p<0.001 for all treatment comparisons). The proportion of patients with an increase of
>200mL from baseline in trough FEV1 at Week 26 (LOCF) from baseline was greater for
QVA149 (39.8%) compared with indacaterol (26.2%), glycopyrronium (23.8%), tiotropium
(25.1%) and placebo (8.4%), (p<0.001 for all treatment comparisons).
Secondary analyses
FEV1 area under the curve [AUC]0–12 h was significantly greater in the QVA149 treatment
group compared with placebo and the active comparators at Day 1 (all p<0.001; table 2). At
Week 26, QVA149 provided significant improvements versus placebo and the active
comparators in FEV1 AUC0–24 h (all p<0.001) and FEV1 AUC12–24 h (all p<0.01; table 2).
3
QVA149 demonstrated a statistically significant improvement in FEV1 2 hours post-dose
compared with placebo and all active comparators at Week 26 (p<0.001; table 2).
Inspiratory capacity was statistically significantly greater in the QVA149 treatment group
than in the placebo group at all assessed time points including Day 1 (LSM treatment
difference: 0.18 L–0.28 L), Week 12 (LSM treatment difference: 0.24 L–0.32 L) and Week
26 (LSM treatment difference: 0.16 L–0.31 L).
Trough forced vital capacity (FVC) was significantly greater in the QVA149 group at Day 1,
Week 12 and Week 26 compared with placebo, indacaterol, glycopyrronium and tiotropium
groups (all p<0.001; appendix figure 2). Improvements in FVC were statistically significantly
greater with QVA149 versus placebo at all assessed timepoints on Day 1 and at Weeks 12
and 26 (all p<0.001).
Pre-planned subgroup analyses
Additional analyses of trough FEV1 at Week 26 demonstrated that data for the subgroups of
age, gender, severity of chronic obstructive pulmonary disease (COPD) and baseline ICS use
were similar to those of the overall population (appendix figure 3).
Dyspnoea
The proportion of patients achieving a minimal clinically important difference for TDI score
(improvement of ≥1 point [1]) at Week 26 was significantly greater in the QVA149 group
(68.1%) compared with placebo (57.5%; p=0.004) and tiotropium groups (59.2%; p=0.016;
appendix figure 5). Significantly greater proportions of patients receiving QVA149 achieved
improvements in TDI score of ≥2 points (p=0.004) and ≥3 points (p=0.019) compared with
placebo at Week 26 (appendix figure 5). More than half (56.7%) of the QVA149 patients had
major improvements (≥3 points) in TDI focal score (appendix table 4).
Health status
An improvement in SGRQ total score was seen at Week 12 with QVA149 compared with
placebo (LSM difference: –3.99; p<0.001), glycopyrronium (LSM difference: –1.84;
p=0.020) and tiotropium (LSM difference: –2.37; p=0.003). The proportion of patients
achieving the MCID for SGRQ total score (≥4-point reduction [2]) at Week 26 was
significantly greater in patients receiving QVA149 compared with those receiving tiotropium
(p=0.047 [appendix table 5; appendix figure 5]). Additionally, significantly greater
proportions of patients receiving QVA149 or indacaterol achieved improvements in SGRQ
total score of ≥8 compared with placebo, glycopyrronium and tiotropium at Week 26 (p<0.05
[appendix table 5; appendix figure 5]).
